Simulation and Design of a 40 GHz Mach-Zehnder Modulator on InP
نویسندگان
چکیده
Based on a rigorous vectorial analysis, a fast traveling-wave Mach-Zehnder modulator is modelled and designed. The cross-section of the semiconductor layer stack and the lossy electrodes are carefully modelled using the Method of Lines in order to investigate propagation characteristics, velocity and losses. In order to enhance the modulation efficiency, design curves are derived and the cross-sectional dimensions for minimum microwave loss are determined. The loss of the optimized modulator agrees very well with Small Signal measurements up to 40 GHz. The layerstack of the fabricated device is suitable for integration with InP multi-wavelength lasers.

High-Speed, Low-Driving-Voltage Dual-Drive InP-Based Mach-Zehnder Modulator
We present a dual traveling-wave electrode InP-based Mach-Zehnder (MZ) modulator with an n-i-n waveguide structure. An electrical input/output interface placed on one side of the chip helps us to drive the modulator in a push-pull configuration. This configuration provides the modulator with great advantages such as reduced driving voltage amplitude, chirp-free operation, and the ability to sup...

متن کاملHybrid InGaAsP-InP Mach-Zehnder Racetrack Resonator for Thermooptic Switching and Coupling Control.
An InGaAsP-InP optical switch geometry based on electrical control of waveguide-resonator coupling is demonstrated. Thermooptic tuning of a Mach-Zehnder interferometer integrated with a racetrack resonator is shown to result in switching with ON-OFF contrast up to 18.5 dB. The optical characteristics of this unique design enable a substantial reduction of the switching power, to a value of 26 m...
